Add support for `gmd:status`

[streino]

I'd like to suggest adding support for gmd:status.

ISO-19115:2003 definitions

gmd:status: status of the resource(s)
gmd:MD_ProgressCode: status of the dataset or progress of a review

Example

<gmd:identificationInfo>
  <gmd:MD_DataIdentification>
    <gmd:status>
      <gmd:MD_ProgressCode codeList="http://standards.iso.org/iso/19139/resources/gmxCodelists.xml#MD_ProgressCode" codeListValue="onGoing">
      </gmd:MD_ProgressCode>
    </gmd:status>
  </gmd:MD_DataIdentification>
</gmd:identificationInfo>

Rationale

It is not clear if and how this metadata should be supported because it is not mentioned at all in the INSPIRE Technical Guidelines and is defined as optional in the ISO-19115:2003 spec (I don't have access to the ISO-19139 spec but assume it's the same based on the schemas).

However, I believe it would be worth supporting because:

• It is useful metadata, found in the wild in a number of INSPIRE catalogs (from the French administration at least).
• It is mentioned in the GeoNetwork documentation in a page dedicated to INSPIRE, and therefore likely to be used in that context.
• The adms:status metadata in GeoDCAT-AP seems like a good fit¹ and doesn't yet have a mapping in the spec.

---

I wanted to go ahead and propose a PR for this, but I believe the spec needs work first:

• Mapping from ISO to DCAT needs to be clarified².
• The "distribution status" EU vocabulary mentioned in section 10.3 of the spec is missing a number of entries to map the gmd:MD_ProgressCode codelist.

Footnotes

1. As suggested by https://www.w3.org/TR/vocab-dcat-3/#life-cycle. ↩ ↩²

2. Mentions of adms:status in GeoDCAT-AP are inconsistent: It is specified only at the level of CatalogRecord as "change type" in section 7.3, but is then only mentioned as part of Distribution in section 10.3. No mention at the CatalogedResource level, despite DCAT mentioning it in its life-cycle¹. The spec also doesn't provide any example for this metadata. ↩

Definitions of gmd:status and gmd:MD_ProgressCode in ISO 19115:

To facilitate discussion on the mapping to DCAT-AP / GeoDCAT-AP, I am providing below the different values gmd:MD_ProgressCode codelist may adopt:

• completed: production of the data has been completed
• historicalArchive: data has been stored in an offline storage facility
• obsolete: data is no longer relevant
• onGoing: data is continually being updated
• planned: fixed date has been established upon or by which the data will be created or updated
• required: data needs to be generated or updated
• underDevelopment: data is currently in the process of being created

[streino]

The EU vocabulary lists the following terms:

• COMPLETED: This distribution is considered to be complete, it holds all information that is intended.
• DEPRECATED: It is recommended that the contents of this distribution no longer be used.
• DEVELOP: This distribution is currently being assembled. It may be in an incomplete or faulty state.
• WITHDRAWN: This distribution is no longer meant to be published.

Tentative mapping, only looking at the definitions above, and only to get a rough idea of what's missing:

MD_ProgressCode	distribution-status
completed	COMPLETED
historicalArchive
obsolete	DEPRECATED
onGoing
planned
required
underDevelopment	DEVELOP
	WITHDRAWN

Just found out from an old DCAT-AP thread that, in addition to the Distribution status vocabulary previously mentioned, there is also a Dataset status vocabulary.

It includes the same terms as Distribution status, plus:

• DISCONT: This dataset is no longer produced or updated.
